worm gearbox:DGAB series torque from four hundred-48000N.m,
D sequence torque from 2000-180000 N.m
merchandise design principles
1.shell:
Dagong shall at least adopt the shell made of ductile iron, which can bear the extreme load in the earthquake location, with IP67 sealing grade, and the exposed parts shall be corrosion-resistant or the surface shall be protected with gray epoxy resin. Available in carbon steel, stainless steel, corrosion-resistant alloy and high and low temperature
environment materials, including deep sea worm gear.
2.ワーム:
wear-resistant nodular cast iron worm gear is matched with alloy steel worm gear, manufactured with improved
process data after multiple process evaluation,
and equipped with large-grade grease or lubricating oil which makes the worm gear wear- resistant continuously, prolongs the service life of the product future enhances the switching torque characteristic and transmission efficiency applicable to the valve, and reduces the input torque. The large reduction ratio makes each pair of worm gears suitable for the self-locking capacity required by the valve to control the valve. Bronze worm gear and alloy steel worm gear are available.
three.mechanical restrict and seal:
The travel limit screw with an angle of -90°( ±5°)can be adjusted to satisfy the requirements of the valve switch.the altering screw seal is recognized by the invention patent of the university of the technologies,which can ensure a variety of environmental seals ,this kind of as higher temperature ,reduced temperature,deep sea,substantial and lower force,constant force and strong corrosion setting.in the larger security amount,the safety cap can be utilised to obtain double sealing.
4.Reduction gearbox:
the style of the gear strives to make the root anxiety of the two wheels equal,to meet the instantaneous torque characteristics when the valve is opened and closed,and to increase the put on period of time of the pinion.the principal reduction equipment employs the huge module cylindrical gear,and the planetary equipment is used to decrease the massive specification and large torque to accomplish the needed input torque.they can be utilised for handwheel operation,sprocket procedure and electric push gearbox.the gearbox design have a specific place to fulfill the simultaneous decoding time of the electrical set up when selecting different transmission ratios.
五。output flange:
The design standard of the output flange related with the valve shall be in accordance with ISO 5211.each specification gives numerous flange options to satisfy the connection needs of the valve.
六。output shaft hole:
In accordance to ISO 5211 standard ,the output push gap can be directly tailored in various dimensions with out added machining to satisfy the assembly specifications of the valve stem.Give numerous relationship strategies,these kinds of as multi essential link,diagonal square head,parallel square head,flat head,spline relationship,and so forth.
7.input shaft for handwheel procedure:
for the input shaft of the gearbox operated by the hand wheel ,anti-corrosion security therapy shall be carried out or the stainless steel substance shall be used straight .the lock gadget and 2-inch handwheel block driving components can be specified .According to the valve torque,the wheel specification can be selected,so as to meet up with the needs that the operating drive of the driving valve is not higher than that specified by the valve.
8.all items are geared up with loc ept device:
It can be locked at any time when the internet site demands to meet up with the specifications of the wor ept problems
